Specification of Letters Patent.

Patented Sept. 11, 1917 Application filed July 29, 1916. Serial No.111,982.

To all whom it may concern:

Be it known that I, EDWARD L. Boson- MAN, a citizen of the UnitedStates, and a resident of East Orange, in the county of Essex and Stateof New Jersey, have invented certain new and useful Improvements inTrucks, of which the following is a specification.

The objects of this invention are to provide a truck which, when loadedwith a particular article, will indicate whether that article is fullweight; to provide such a truck adapted for receiving bags of cement; toaccommodate a plurality of such bags of cement or other articles; toindicate as each bag is loaded whether it is of full weight; to thuspermit discarding a short weight bag before another is loadedfrom thebag filling machine; to break the fall of the bags from the machine soas not to break the bags; to employ resilient means for this purpose; toprovide a truck which is readily handled; to adapt the truck to be selfsupporting or manually supported as desired; to provide a strong anddurable constructlon, to secure simplicity of construction andoperatlon, and to obtain other advantages and results as may be broughtout in the following description.

Referring to the accompanylng drawlngs in which like numerals ofreference indicate the same parts throughout the several views,

Figure 1 is a side elevation of a loaded truck embodying my invention;

Fig. 2 is a similar side elevatlon of an unloaded. truck folded Fig. 3is a front elevation of the truck open and unloaded;

Fig. 4 is a longitudlnal sectlon of one of the side members showing thespring and rider mounted therein;

Fig. 5 is a longitudinal section of the rider, and

Fig. 6 is a transverse cross-section on line 66 of Fig. l;

In the specific embodiment of the inven tion illustrated in saiddrawings, the reference numeral 1 indicates the body portion of a truckframe mounted upon wheels 2, 2 and adapted to be supported in inclinedposition by a third wheel 3 at the lower end of a prop 4: From the frontof the body portion of the frame, that is, the side of the body portionopposite from the prop, pro ects a tray 5 upon which articles to betransported, such as the bags of cement 6 shown, are placed.

It is to be understood, that the tray is to be considered forconvenience, as projecting from the front of the truck, in which casethe prop will be seen as arranged at the back of the truck.

Described in greater detail, the frame comprises preferably a pair ofseparated side members 7, 7 shown as continuously tubular from one endto the other. These side members are held rigidly by a plurality ofcross braces 8, shown as bars extending between the side members andlooped at their ends over said members and riveted or otherwise held toclamp the loops. At the back of the body portion of the frame aresuitable handles 9, 9, the same being shown as riveted to the back ofthe upper cross brace 8, projecting upwardly and rearwardly therefrom.Preferably, also the material forming the shank of each handle dependsbelow the brace 8 to which it is secured and is looped around a hingerod 10 which extends transversely of the frame between said depending orlooped portions of the handles and projecting beyond the same. Uponthese projecting ends of the hinge rod are pivoted the upper ends ofspread apart legs 11 of the prop. These legs converge downwardly and,for greater strength, are riveted or otherwise held together near theirlower ends, and then spread apart again enough to receive the wheel 3therebetween.

Preferably, in order to restrict the distance which the prop may swingaway from the body portion, a lip 12 projects upward above the hinge rodfrom each leg adapted to engage the cross brace or side member at thedesired position of the prop. For greater rigidity, check means areprovided for the prop adjacent the wheel if desired, comprising ajointed arm 13 in the present disclosure, hinged between the legs of theprop on a rivet or the like 14: holding said legs together and alsohinged to one of the cross braces of the body portion of the frame, asat 15. Said arm is adapted to bend intermediate of its length uponahinge pin or rivet 16 so that the prop may be swung toward the bodyportion of the frame when so desired. Coacting stops 17, 18 are providedon the two portions of the arm adapted to prevent the said portionsfrombeing bent past alined position.

At the front of both side members of the frame are provided longitudinalslots 19,

plied to the tray,

19 from the bottoms of said members to about midway of their length. Asnoted above, the members are hollow, and slidably contained therein areriders 20, there being one .rider in each member. The tray 5 isconnected to and supported by these riders, the side arms 9.1, 21 of thetray projecting through the slots and being attached to the riders.Obviously, therefore, by this construction the tray may be movedlongitudinally of the side members of the frame. The riders are madelong enough to hold the tray in substantially the same angular relationto the side members of the frame at all times. By this construction andbecause of the definite angle at which the frame is held to thesupporting surface by the prop, the tray 5 will always be lowered agiven amount for definite weight, because the component of gravityacting parallel to the frame will be proportionate to the actual weightof the load always in the same ratio. It is to be understood, that thetray moves up and down or longitudinally at the front of the frame, andwhen completely loaded is at the bottom of said frame but does notproject beyond the end or below the same, and consequently will notinterfere with wheeling the truck around.

In order to obtain a free sliding'movement of the riders, the same arepreferably provided with rollers or the like, and I have shown one suchroller 22 near the bot-tom of each rider adapted to bear against theinner wall of the member opposite the slot. Near the top of the riderare two other rollers 23, 23 arranged to bear against the inner wall ofthe member adjacent the slot on opposite sides thereof. Obviously a loadupon the tray will tend to swing the upper end of the rider forward andthe lower end back- .ward, so that the rollers engage the wall of themember and reduce the resistance to sliding'of the rider.

The rider preferably is provided with a resilient support so that as theload is ap- Y the tray is lowered, but returns to its uppermost positionwhen the load is removed. To this end I have shown a spiral spring 24attached at its lower end to the upper end of the rider, said springbeing fixed at the upper end of the member 7 by being hooked into theeye 9.5 of a cap 26 closing the upper end of said member.

Preferably means are provided for indicating whether or not each articleis of full weight, and for this purpose scale markings 27 are made uponthe members at the point to which the tray should lower for the correctweight of package. For a standard package, such as cement bags shown,short weight can-be detected as the bag is loaded. In use it is intendedthat the bag pass directly from the bag filling machine to the truck,and the workman can remove a bag I a wheeled frame having tubularimmediately which shows by the scale to be of improper weight beforeanother comes from the machine.

In; addition to the advantage obtained by the spring support for thetray to check the weights of the bags, the resiliency breaks the fall ofthe cement bags from the machine to the truck, and particularly breaksthe fall of the first bag, and greatly reduces the likelihood of thebags bursting.

Obviously detail modifications and changes maybe made in the manufactureof my improved truck without departing from the spirit and and I do notwish to be understood as limiting myself except as required by thefollowing claims when construed in the' light of the prior art.

Having thus described the invention, what I claim is,

1. In a truck of the character described, a

scope of the invention wheeled frame, a load supporting tray pro jectingfrom said frame and connected thereto so as to slide longitudinally ofthe frame without projecting beyond the end thereof, and springsresiliently supporting said tray. I v j 2. In a truck of the characterdescribed,

side members longitudinally slotted, a tray with' arms extending intosaid slots so therein, and springs in said tubular side membersresiliently supporting said tray.

as to slide 3. In a truck of the character described,

a wheeled frame having hollow side menibers, a tray for supporting aload, riders in said members adapted to support the tray and retain itin the same angular relation to the side members, and springs also insaid members for resiliently supporting the riders.

4. In a truck, a wheeled frame having hollow side members, a tray forsupporting a, load, riders in said members adapted to support the trayand retain it inthe same angular relation to the side members, saidriders having rollers adapted to engage the members and reduce thefriction whereby the riders may slide freely, and springs alsd in saidmembers for resiliently supporting the riders.

5. In a truck, a wheeled frame having hollow side members withlongitudinal slots, a tray for supporting a load having its side armsprojecting through said slots, riders in the members receiving said armsand. thereby supporting the tray in transverse relation to the members,and springs also said members resiliently supporting theriders wherebythe same may slide down iii' the members as a load is applied to thetray load and adapted to slide longitudinally of the frame when a loadis applied, and means for holding said frame at a certain angle to thesupporting surface whereby a load of a given Weight will always slidethe tray to a certain position with respect to the frame under theaction of gravity.

7. In a truck of the character described, a wheeled frame, a tray forsupporting a given weight will always slide the tray to a certainposition with respect to the frame under the action of gravity, saidmeans being collapsible toward the frame.
